Servlet: weird cookie string

I'm running my servlet on Tomcat 7. When retrieving cookies with the request.getCookies(); the values returned are weird strings "8267663C31A2F33C16B7C0D864874DC4"

Can anyone 开发者_JS百科tell me what this is?

Output from 2 text form data:

8267663C31A2F33C16B7C0D864874DC4

8267663C31A2F33C16B7C0D864874DC4

Thanks,

That looks very much like a session ID. Is the name of that cookie "JSESSIONID" ?

Probably looks like a jsessionid used for associating a given user with a servlet session on the server side.
